Write a Java program such that it consists of 2 classes: 1. a class that serves as the driver (contains main()) 2. a class that contains multiple private methods that compute and display a. area of a triangle (need base and height) b area of a circle (use named constant for PI) (need radius) c. area of rectangle (width and length) d. area of a square (side) e. surface area of a solid cylinder (height and radius of base) N.B. You will also need an accessor public method (interface) that is called from the driver. This method should: a. Display a menu of options to the user. (Suggest use switch statement) b. Accept input from the user (keyboard) representing parameter values needed.

Directions: SHOW ALL YOUR WORK. REMEMBER THAT PROGRAM SEGMENTS ARE TO BE WRITTEN IN JAVA. Notes: • Assume that the classes listed in the Java Quick Reference have been imported where appropriate. • Unless otherwise noted in the question, assume that parameters in method calls are not null and that methods are called only when their preconditions are satisfied. • In writing solutions for each question, you may use any of the accessible methods that are listed in classes defined in that question. Writing significant amounts of code that can be replaced by a call to one of these methods will not receive full credit. Consider a guessing game in which a player tries to guess a hidden word. The hidden word contains only capital letters and has a length known to the player. A guess contains only capital letters and has the same length as the hidden word. After a guess is made, the player is given a hint that is based on a comparison between the hidden word and the guess. Each position in the…

Write the definition of a classTelephone. The class has no constructors and one static method printNumber. The method accepts a String argument and prints it on the screen. The method returns nothing. 1 class Telephone 2-{ 3 public static void printNumber (String s) 4- { 5 System.out.println(s); 6 } 7 } 8 public class Main 9- { 10

Question Two Write a java program that prints student's name, grades and GPA. You must do the following requirements: 1. Create three methods: a. First method to accept and print your first, last name, and GPA. 2. Call the three methods you created above in your main method. b. Second method Markt and print your grades Marks of three courses (type: int) 3. Create a method without parameters that would return only your GPA. The method should be named with your last name followed by GPA (e.g., AlwalledGPA()). Note: c. Third method to overload the second method (types: double). The method must print your grades. 4. Declare a double variable that holds the returned value of the last method you created. 5. Print the value of your GPA variable. Help ● The class name of your Java program must be your first name. • Your answer should have the code as text as well as the screenshot of the program output (using your own name) as a part of your answer. Otherwise, zero marks will be awarded.…

Code in JAVA and see attached images for information on classes and methods A company pays its personnel on a weekly basis.  The personnel are of 4 types:  FixedWeekly personnel are paid a fixed amount regardless of the number of hours workedByTheHour  personnel are paid by the hour and receive overtime pay for all hours worked in excess of 40PercentOfSales personnel are paid a percentage of their salesFixedWeeklyPercentOfSales personnel receive a fixed amount plus a percentage of their sales. Create a class called Personnel.  This class will represent the general concept of all personnel.  All 4 types of personnel are considered Personnel.  FixedWeeklyPercentOfSales personnel are considered to be PercentOfSales Personnel.   The Personnel class will also be Payable.  You will need to create the Payable interface.  It will contain just one method called earnings().   Test Run Personnel processed polymorphically: FixedWeekly personnel: Harry Clarksocial security number: 111-11-1111weekly…

python program Design a class for an airline ticket. Some of the field of an airline ticket are start, destination, date of travel, class, price of ticket, number of people traveling, and name of the primary person. Think about the methods appropriate for the class. Add one method call reserve, which will take details of passengers, start date, starting point, destination and other related attributes and returns flight details.

java  a. You want to create a Java main class. You create the source code file, declare the package, and write the class header. Now you must create the main method that starts the program. Write the entire method header, including the opening brace for the method. b. Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Write a statement that calculates the whole dollars in the amount and saves it in a new integer variable named dollars. Note: The Java style guide states that one space is used on either side of binary operators.
